中文摘要	【目的】探明甘家湖梭梭和白梭梭的种群结构及其数量动态,探讨其未来发展趋势,并分析甘家湖梭梭和白梭梭种群的空间分布格局。【方法】本研究在甘家湖自然保护区设置了大小为50 m *50 m的梭梭和白梭梭样地,利用种群生态学方法、点格局分析方法和统计学方法,分析了甘家湖梭梭和白梭梭种群的生长特征及各生长指标之间的相关性,揭示不同样地内梭梭和白梭梭种群的空间分布格局。【结果】①甘家湖梭梭和白梭梭种群的基径呈倒J型,幼苗和幼树的个体所占比例较高,种群结构为增长型; ②甘家湖梭梭和白梭梭种群的静态生命表均表明低龄级的个体数较多,2种植物的存活曲线均趋近于DeeveyⅠ型(凸型),种群属于增长型; ③甘家湖梭梭和白梭梭种群分别在0 ~ 2和0 ~ 3 m的尺度上呈聚集分布,在其余尺度上呈随机分布。【结论】甘家湖梭梭和白梭梭种群处于稳定发展阶段,且种群的自然更新能力及稳定性较强,并呈现出在较小尺度范围内聚集分布的空间分布特征。
英文摘要	【Objective】The present paper aimed to investigate the population structure and quantity dynamics of Haloxylon ammodendrons and Haloxylon persicum in Ganjia lake,to explore their future development trend and to analyze the spatial distribution pattern of H. ammodendron and H. persicum in Ganjia lake.【Method】In the study,two H. ammodendrons and one H. persicum plots with a size of 50 m *50 m were set up in the desert area of Ganjia nature reserve,the growth characteristics and correlation between various growth indicators of H. ammodendron and H. persicum populations in Ganjia lake were analyzed,and the spatial distribution patterns of H. ammodendron and H. persicum populations in two plots were analyzed by various methods.【Result】(i) The base diameter of the H. ammodendron and H. persicum populations in Ganjialake was invertedJ,seedlings and saplings had a higher proportion of individuals,and their population structure was growth; (ii) The static life tables of the H. ammodendro and H. persicum populations in Ganjialake indicated that the number of individuals in the lower age class was higher,and the survival curves of the two plants were close to Deevey I,and the population was growth; (iii) The populations of H. ammodendron and H. persicum were clustered at 0 - 2 and 0 - 3 m,respectively,and randomly distributed on other scales.【Conclusion】The populations of H. ammodendron and H. persicumin Ganjia lake are in a stable development stage,the natural regeneration ability and stability of the populations are strong,and the spatial distribution characteristics of aggregation distribution are in a small scale range.
